Not sure if this has been discussed already but what do you guys think about having some time to spend in the vault and seeing how you become the sole survivor of Vault 111 before getting into the game, just like in Fallout 3 how you started in the vault getting to know the basics of survival and the dangers before finally emerging to the main gameplay.

I personally would find this really cool because it can add more to the story and I am curious to what other people think about this idea.
